HUMAN NUTRITION

Detailed explanation-1: -Beta cells are cells that make insulin, a hormone that controls the level of glucose (a type of sugar) in the blood. Beta cells are found in the pancreas within clusters of cells known as islets.

Detailed explanation-2: -Insulin is secreted by the -cells of the pancreatic islets of Langerhans in response to elevation of the intracellular Ca2+ concentration ([Ca2+]i). This is produced by an influx of extracellular Ca2+ via voltage-dependent Ca2+ channels, whose activity, in turn, is regulated by the -cell membrane potential.

Detailed explanation-3: -Insulin is a hormone produced in the pancreas by special cells, called beta cells.

Detailed explanation-4: -Beta cells have an average diameter of 10 m, contain about 20 pg insulin per cell, and are the predominant cell type in the pancreatic islets (50–80% of all islet endocrine cells) (Marchetti and Ferrannini, 2015).

Detailed explanation-5: -Beta cells produce insulin, a hormone necessary for cells to absorb and use glucose, a type of sugar that circulates in the blood and serves as cellular fuel.
